const_cast operator

const_cast operator Cast to modify qualifiers

postfix-expr := const_cast < type-id > ( expression )

The const_cast operator performs a type cast that can add or remove const and volatile qualifiers. No other modifications to the type are permitted.

If you cast away a const or volatile qualifier from an object, and then modify the object, the behavior is undefined.


template<typename T>

T& unsafe(const T& x)


  return const_cast<T&>(x);
